ELECTRIC Specication of FIXTURE.

Letters Patent Patented June 2l 1910.

Application filed September 15, 1909. Serial No. 517,871.

'1b all whom it may concern:

Be it known that I, Gnome Fnnmnuok .li-Usn, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State oflllinois, have invented a certain new and useful Improvement in ElectricFixtures, of which the following is a specifcation.

This invention relates to electric fixtures and is in some ways animprovement or a modification of that of my prior application, SerialNo. 494,966, filed May 10, 1909.

The object of the invention is to provide an electric fixture,preferably of porcelain or other similar material, presenting a pleasingand useful surface to the room in which it 1s located in which theelectric light bulbs are attached thereto and protected and insulated bythe fewest possible number of parts, and in which the parts are securedtogether in a very rigid and satisfactory manner but so that they may beseparated and detached for repair and the like.

The invention consists in mechanism for carrying out the foregoinginvention which can be easily and cheaply made and assembled, therebyinsuring satisfactory operation and doing away with a large number ofparts heretofore used.

It also consists in more specific details of construction which will behereafter more fully described and claimed as the specificationproceeds.

Referring to the drawings, Figure 1 is a vertical sectional side view ofone of'the forms of device illustrating this invention. Fig. 2 is ahorizontal plan view taken on the line 2-2 of Fig. 1. Fig. 3 is aperspective detail view of one of the contact members. Fig. 4 is avertical sectional detail View of the preferred form of construction.Fig. 5 is a plan view on the line 5-5 of Fig. 4. Fig. 6 is a perspectivedetail view of one of the contact members. Fig. 7 is a perspective viewshowing the referred fixture of Fig. 4 applied to the wa of a room.

In the form of this invention shown in Fig. 1, as in the above mentionedprior application, the portion exposed to the room consists essentiallyof a flat plate member 10 of porcelain or other similar materialsecuredv directly to the wall proper 12 by means of the screws 14 orother suitable devices. The front face 16 of this Xture may be washedand decorated with calcimine said prior application, and the electriclight bulb proper enters a dome 18 or other inclosing device but thisdome is not, as in the prior application, made integral with the frontplate 10 but is, instead, attached thereto by means of the metallicstraps 20 having one end bent through the'opening 24 and around theportions 26 of the dome 18, thereby doing away with the necessity forthe use of rivets, screws and the like. The opposite ends 28 of thesemembers 20 lie between the front plate 10 and the wall 12 and arepierced by the screws 14 whereby the one set of screws 14 serves to holdthe dome 18 in substantially as rigid contact with the member 10 asthough the dome and the member 10 were made integral. This making thedome separable has advantage over the construction of the priorapplication in that a larger dome may be used containing lnore electricdevices Without marring the front of the plate- 10 and that suchelectric devices can be more readily installed within the dome than inthe structure illustrated in said prior application. The face plate ormember 10 heretofore described has in it a circular perforation for thecontact end 30 upon the electric light bulb 32, as shown, saidperforation or hole having its outer portion flaring in the angular'surface 34 and its inner portion 36 straight, as shown. In this openingthere is placed a metallic member 38 having its upper portion screwthreaded, as shown, and its lower portion bent into the outwardlyflaring flange 40 registering with the inclined face 34 in the frontplate 10 heretofore described. Threaded upon the upper screw threadedportion of this metallic member 38 is a wrench like member 42 having anarm 44 extending therefrom. From the foregoing it will readily be seenthat by first inserting the member 38 in the above described opening inthe member l0 and then threading the Wrench member 42 thereon and usingthe member 44 as a wrench handle, if desired, the flaring portions 40 inthe member 38 can be brought into very close contact with the inclinedface 34 of the plate member 10, whereby the metallic member 38 issecurely locked in working position in said plate. /Vhen this adjustmenthas been made or rather as it is completed the member 44 is Figs. 1 and2, where it readily contacts with or the like, as in the case of thefixture of the contact block 46 of an ordinary com'- brought around tothe position shown in mercalswitch comprising a shaft 48,- the yoke 50,the spring contact 52, mounted within the dome 18, said shaft 48 andconsequently the switch being rotatable by use of the handle 54 mountedupon the outside of the front plate 1() in the ordinary manner so thatrotating this handle makes and breaks contact between the members 44 and46, thereby controlling' the passage of electricity which entersA theswitch device through wires, not shown, attached by the screw contact 56to the exterior contact portion 30 of the lamp 32. In line With thecentral` axis of the lamp 32 is a central contact member consisting ofthe plate 58, a U shaped member 60 and a tubular member G2 extendingtherefrom into the dome 18 proper Where it is secured in position by thebolt 64 and the nut 66, as best seen in Fig. 1. At the turn ot` this Ushaped Inem ber 60 is the contact member 68 located near the adjacentopening 24 in the dome so that a wire may be inserted and attached bymeans of the screw 69 to this member, thereby admitting electric currentto the plate 58 and thence to` the central contact 70 of the lamp 32.This member just described and illustrated fully in Fig. 3 is made fromone piece of metal, the member 62 having ay slot 72 along one verticalside, said slot being formed by the adjacent edges of the original llatpiece of metal brought in contact with each other as the member 62 isbent up and the plate 58 is formed by having its flange 74 bentdownward, as shown.

In the preferred form of construction shown in Fig. 4 the front plate 76is provided, having inserted through an opening therein a threadedmetallic member 78, having the flaring flange 8() engaging the `inclinedface 82 of the front plate 76 exactly as in the form of Fig. 1. Insteadof using the wrench member 42 as a tightening device the dome 84 itselfso acts and is screw threaded, as shown, at 86 upon the upper portion ofthe member 78, the member 78 being locked in contact with the member 76by rotating the dome 84. The dome 84 is provided With side perforations88, as shown, through which electric Wires, not shown, are adapted y tobe passed to the screws 90 and 92 entering respectively the conductingmembers 94 and 96. Themember 94 is rigidly connected by any suitablemeans to the screw threaded member 78 with which the exterior contactportion 99 of the lamp 100 contacts. The member J6 is bent into the llatportion 102 and the tubular portion 104 through which the current iscarried by the screw 106 insulated by the lava or other insulatingthimble 108 from the bolt 110, whichin turn directly contacts with thecentral contact member 112 of the lamp. The result of this preferredform of construction is that by the aid of a very small number of partsthe dome while separable is readily attached to the front plate 76,While the dome positively secures to the front plate a metallic member78 in which the lamp is directly mounted. The connector illustrated in I`ig.v8 may also be substituted inside the dome of Fig. 4 and ispreferably so used to lessen the number of parts.

rlhe claims are l. In adevice of the class described, the combination ofa front member of insulating material adapted to be exposed to the roomhaving an opening therethrough for an electric lamp, a lining member ofcorresponding shape inserted in said opening, there being an enlargementupon the outer end of said lining member which prevents its passingentirely through the front member, and a dome of insulating materialheld upon the rear of the front member by locking engage! ment With thelining member, there being space Within the dome for electric connee.

tions for a lamp which may be inserted through the opening in the frontplate member.

2. In a device of the character described, a front member adapted to beexposed to the room havin an opening therethrough for an electric amp,said opening flaring toward the room side of the first mentioned member,a lining member of corres ending shape inserted in said opening, a omeof insulating material upon the rear of the first mentioned member screwthreaded upon the lining member to lock it in position and means Withinthe dome for conveying electric current to and from a lamp inserted inthe opening in the rst mentioned member.

In witness whereof, I have hereunto subscribed my name in the presenceof tWo Witnesses.
